I need one like i need a hole in my head BUT I absolutely hate being told what I need or get to own. So I just recieved a couple of 60rd mags. Echo II trigger should be here soon. Not sure if i will even install it but by God I will have one. And once things calm down i will own a bump stock also. Again might not put it on anything but i will have one. Just how my mind works. Drives my wife crazy at times.
